Britt Beemer’s America’s Research Group was commissioned by Ken Ham to survey 1,000 former attendees of conservative Christian churches, who are now in their twenties, to discover why they left. Already Gone is a summary of the survey results, and a challenge to the church to heed the warning and make the radical changes required to remain relevant – not only to the younger generations, but to everyone.

Do you believe in the authority of Scripture? Does your life demonstrate it? Ken Ham poses these questions to young adult Christians both in and out of mainstream churches, to pastors, Christian teachers, to parents, churches, and educational institutions. The subject of Already Gone is the generation of Christians my age (20’s), many of whom have left the church. Of those who have left, there are two main groups: one whose worldview is mostly secular and skeptical of the Bible, and one that believes the Bible is true and applicable but has found the church irrelevant. How is the church failing to deliver a biblical worldview to the children and youth who faithfully attend Sunday school, church, and youth group? Of the twenty-something’s who remain in the church, are they submitted to the authority of Scripture, or is their search for a worship experience prevailing over God’s teachings about the Body of Christ?

What about the parents, pastors, youth pastors, and Sunday school teachers who make up the older generation, the church establishment? Have they sold out God’s teachings on the church for their beloved traditions? How much of what we think of when we hear “church” is actually biblical? Why is the most common accusation against the church that it is hypocritical? The church in America is losing members so drastically that we need to radically reevaluate our practices and teachings. Compromise cannot be tolerated.

As founder of Answers in Genesis, Ken Ham must touch on his favorite subject: the foundational importance of Genesis, and how compromise on the historical and scientific truth of Genesis undermines all of Scripture, faith in God, and even the gospel. He calls the church back to teaching “earthly things,” the correspondence between the Bible and reality. Christians need to be equipped for apologetics from an early age, to guard against doubts and to answer inquiries from a godless culture. This, more than music or games or attractive activities, is the only way to be relevant to people living in the real world and desperate for answers.

Already Gone is a fair, factual, and interesting treatment of the systemic problems in the church today. Lest we become like post-Christian Europe, where church is a marginal pastime for a few elderly people clinging to vestiges of tradition in empty cathedrals, we must take action now. Several reactions to the problem are presented, with their disadvantages and perks, but ever a challenge to study for yourself what God says about church and training up children.

As a member of the generation under the microscope, on the edge of the traditional church and ready to flee, I was impressed by the willingness to take us seriously. Some of us are leaving because we see the problems and want a church that does what a church should, and loyalty isn’t strong enough to keep us from looking outside our experience. Ken Ham acknowledges, with some surprise, people in my situation. I appreciated this book. Even though I’m pushing for the more extreme reactions mentioned (abandoning Sunday school and traditional trappings: buildings, sermons, and orders of worship), I have a lot of respect for the way Already Gone ties the whole malady to the failure of Christians to teach and obey the authority of the Word of God. If a person is faithful to study and submit to that, he will be led to the mode of meeting and discipleship God intends, strongly equipped for the Christian call to evangelize our world.
